SEWING-MACHINE FOR FLOSSING.

To aZZ whom it may concern.-

Be' it known that we, J. ALFORD HOUSE and CHARLES H. DIMOND, both of Bridgeport, county of Fairfield, State of Connecticut, have invented an Improvementin Sewing-Machines for Flossing, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the production of a sewing-machine for flossing, as it is called, corsets, and other goods, or for making long stitches back ward and forward, as at the end of steel-receiving pockets of corsets, or at other places where it is desired to ornament corsets or wearing -apparel with thread made to represent long stitches.

The particular features in which our invention consists will be pointed out in the claims at the end of this specification.

Figure 1 is a right-hand side elevation of a machine embodying our invention, the ma chine being mounted upon a table, the latter being partially broken away to show parts behind it. Fig. 2 is a partial lefthand elevation of the head of the machine, the front end of the overhanging end of the frame-work being broken off, the upper parts of the needle and presser bars being also broken away. Fig. 3 is a plan view of Fig. 1, the overhanging arm and table-top being partially broken out to better show some of the moving parts. Fig. 4 is a section of the main part of the machinein the line 00 m, Fig. 3, and of the top of the table. Fig. 5 represents the stop-wheel by itself.

The bed-plate A, the overhanging arm A, the head b, the main or hook driving shaft 33, its eccentric 0 the link 6, pin 0, arm e needle-bar-actuating rock-shaft 0, held in suitable bearings, c" c", the needle-bar 0, connected by an arm and link with the said rock-shaft, needle c, and the take-up D are substantially as in the Vvheeler & lVilson machine style No. 10, so the said parts need not be herein further described, more than to say that the needle 0 will be supplied preferably with floss-silk, which it will pass through the material to form a loop to be entered by the usual rotating hook, (not shown,) the said needle and hook at each complete operation of the needle-bar making a stitch. The main shaft B has fast upon it a stop-wheel or disk, H, (shown separately in Fig. 5,)which is cut away at its periphery to form a shoulder, H against which k,

may be brought,when desired, one end of the elbow stopping-leverH, having its fulcrum on a pin, h of a block, N,attached to the plate A of the machine by screws '11 n, the lower end of the said lever being (provided with a roller, h". wheel is normally kept pressed toward the st0p-wheel by a spring, 2, the latter also acting to keep the roller h pressed toward the pointed cam m, attached to and projecting from one edge of the link m jointed at m to the lever m connected with the rock-shaftm, which rock-shaft has at its other end an arm, m, pivoted to which is a link, at, that in turn is jointed to a treadle, m, pivoted at m on a rod which is extended from one to the opposite leg, m", of the side legs, on the up'- per ends of which the table G is supported. The link m is slotted near its upper end at 4 to receive a guide-pin 5, attached to a station- 8, which projects through on both sides of and is held in an ear, 9, of the bracket 10.

The shaft B has mounted loosely upon it a bandwheel, a, which in practice is driven continuously by a belt extended, as usual, to some driven shaft near the machine. One side of this band-wheel, which always rotates, is kept positively against the fast-shouldered stop-wheel H by a strong spring, 13, acted upon by an adjustable nut, 14, so as to regu late the amount of pressure or friction between the fast and loose wheels, the friction always being sufficient to enable the said loose band-wheel by its engagement with the fast stop-wheel to rotate the shaft B; but the said shaft may be stopped at any time with the needle and presser-foot h lifted by permitting the stop-lever H to turn into its fullline position.

\Vhen the machine is to run and operate, the operator, by her foot upon the treadle, will The end of the lever next the stopkeep the central part, 20, of the cam against the roll ha of the lever H, and will keep the said lever in dotted-line position or lifted from the stop-wheel.

To stop the machine, the operator will move the treadle so as to move the central portion, 20, of the cam away from the roll h and let the spring 2 control the lever H, and as cam m is shaped it is immaterial in which direction the treadle is moved, as the effect will. be the same.

hen working rapidly, the machine has to be stopped and started quickly, and to do this would require an extra amount of attention, and consequently interfere withtherapid manipulation of the cloth by the operator if she had to think in which direction to move the treadle that controls the link W, in order to stop or start the machine.

YVith the pointed cam m-,the operator, by the sensation of feeling exercised through the foot, is enabled by the degree of pressure to know when the pointed part of the cam is against the roll h.

Then the machine is being used to make but one stitch at a time, an upward movement of the link an will cause the point 20 to operate the lever H to release the stop-wheel,and it will make one revolution with the end of the lever H resting against its periphery; but at the completion of one revolution the shoulder of the stop-wheel will strike against the lever H. Next a downward movement ofthe link m will again release the lever H for one more revolution of the shaft B. The shaft B has upon it a cam, j, which at each rotation strikes against a roll, f, on and moves a link, f, connected with a projection, f, of a long partial sleeve, f, which loosely surrounds the needle-bar-actuating rock-shaft O. This partial sleevef constitutes a rock-shaft by which to lift the presser-foot bar 9", the said bar being connected by link 9 with the projecting end f of the said sleeve f". The shaftB is arrested by the lever H to leave the presser-foot lifted, as in Fig. 2, and the needle elevated, so that the material-a stitch having been made and the cloth being free-may be moved by the operator in any desired direction for the distance that it is desired to lay the silk or other thread upon the cloth. A

spiral spring, 0, on the shaft 0, next its rear bearing, a, and connected withit and the rear end of the sleeve, acts normally to turn the sleeve f in the direction to lower the foot h and keep the roll f pressed against the pe 'riphery of the cam j. The throat plate, through which the needle descends, and on which the material being sewed rests, is provided with a needlehole.

\Ve claim 1. The main shaft B, its attached cam f, and shouldered stop-wheel, and the link f, sleeve, and link, and presser-foot bar and presser-foot, combined with a stopdever to arrest the stopwheel and the shaft B with the resser-foot lifted, substantially as described.

2. The main shaft B, the band-wheel loose thereon, the stop-wheel a, fast on the said shaft, and the presser foot and bar, and mechanism, substantially as described, between the said bar and the main shaft to operate the presser-foot, and the spring-plate to force the band-wheel and stop-wheel together to drive the said shaft, combined with the stop-lever, as set forth, to arrest the stop-wheel when loosened.

3."In a sewing-machine, the shaft B, its attached stop-wheel, the band-wheel loose thereon, and spring to force the said band and stop wheels together, and a stop-lever, combined with a' slide-bar provided with a cam and adapted to operate the said lever in one direction, and a spring operating it in the opposite direction, substantially as described.

4. In-a sewing-machine, the shaft B, its attached stop-wheel, the band-wheel loose thereon, and spring to force the said band and stop wheels together, and a stop lever, combined with a slide-bar provided with a cam, the said cam having a point, 20, and inclined surface at either side thereof, whereby the movement of the cam in each direction lets the roller of the stop-lever pass from the point of the cam, thus enabling the end of the stop-lever next the stop-wheel to descend and engage the stopwheel and arrest the movement of the machine, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
